Downloads can be verified using md5sum, a Unix command line tool provided
in the GNU
Textutils package. A Windows binary version is available here.

1. Every download has an associated link "(md5)" to a *.md5
file containing its MD5 checksum. Download this file from the Main
Eclipse download servers into the same directory as the zip file.
2. Execute the command "md5sum -c <zipfilename>.md5".
The result "<zipfilename>: OK" is indicative of an intact
download.
